Patented Nov. 28, 1933 METAL LIQmoooN'rArmiR Frank B. Eilers, Fort Wayne, ImL, assignor to Tokheim Oil Tankand Pump Company, Fort Wayne, Ind., a corporation of Indiana v Application February 3, 1933. Serial No. (Cl. 220- 71) I 1 Claim.

.This invention relates to improvements in metal liquid containers of that type in which lubricating oil or other liquid is held in storage to be dispensed as required, and the walls of which are disposed in flat planes. Such containers, especially'when the Walls thereof are of thin metal, when filled with liquid tend to expand be-v cause of the pressure of the head of liquid within the container against the fiat walls thereof which results in false indications of the quantity of liquid in the container when a gauge stick is employed in the ordinary manner of determining the content of the container by ascertaining the level of liquid therein. Outward bulging of the flat walls of such containers, due to the head of the liquid content thereof, causes lowering of the liquid level in the containers with the consequent inaccuracies in measuring the contents of the containers and interference with grouping of a series of tanks together in compact formation.

An object of the invention is to provide a simple expedient for sustaining the fiat walls of a metallic liquid container substantially in their normal planes to prevent bulging thereof because of pressure within the container occasionedby the head of liquid therein, or, becoming force externally applied by accident or otherwise which would alter the normal quantity holding capacity of the container.

Other objects and advantages of the invention following description. An illustrative embodiment of the invention is shown in the accompanying drawing, in

whicht- Fig. 1 is a perspective view of a lubricating dispenser including a liquid container of a type of which the'invention is applicable and a pump in connection therewith for withdrawing liquid therefrom;

Fig. 2 is a transverse section of a liquid container in which the invention is embodied;

Fig. 3 is a vertical section of Fig. 2 on the line 3-3 thereof;

indented by between the" sides of liquid in the container to the extent ofithe volume of metal forming 7 and'internal pressure to which the container may be subjected.

As an example of theinvention the flat walls 2 of ths container 1 have secured thereto, upon their respective inner faces, corresponding ribs 3 formed convenientlyoi have divergently disposed contiguous sides 4 that terminate, along juncture, with outwardly extending Preferably, the sides their lower ends flanges '5. 4 are of greater width at ends toward their tops. By this formation of the ribs, after being installed permanently in connection with the flat walls aiiord greater resistance to outward pressure against 7 of liquidin the container in the lower portion of said container where the normal pressureis oomparatively" greater than the upper portion thereof. a

tainer and the flanges secured to theinner faces other convenient means whereby said flanges are frequent intervals or throughout their lengths. Thus, a vertical passageway4 4 of each rib and-the adjacent wall 2 to which the rib is secured each end of the rib. terminates atits top and entire portionof the thatis open at Each rib '3.

bottom at corresponding points suitably spaced from the top 6 and bottom 7 of the I container so as to admit of free flowof liquid in the container into and from the passageways. 'Ihus, displacement by the ribs is limited the ribs. V I a In the drawing, the container 1 is shown with a dispensing pump ing a suction pipe 9 extending into the container through whichliquid in the container is withdrawn therefrom as required by operating the pump, and the container is sheet metal shaped tots the edges thereof opposite their.

The ribs are vertically disposed withinthe con-2A thereof are'permanently r of the walls'zby any i U suitable expedient, such as by spot welding or intimately secured to thecorresponding walls atllis left 8 superimposed thereon havil than the tops thereof so that-: the ribs are tapered more or less from theirlower the walls 'of the head:

55 respective planes also rovided in its Fig. 4 1s a side elevation upon an enlarged p scale of one of the braces used in the container structure, a portion thereof being broken away;

Fig. 5 is a top plan view of Fig. 4; and

Fig. 6 is a bottom plan view of Fig. 4.

The illustrative embodiment of the invention consists of a liquid container 1 formed of sheet, metal and characterized by its walls 2 that extend in flat planes and which are sustained in' their by means to oppose external top 6 with a fill opening 10 for replenishing the; container with liquid 'to be subsequently dispensed. In. use, when the container is filled with liquid the more or less extensive walls thereof to which the ribs have been'applied are maintainedsubi stantially in their normal planes and are preventedfrom outward as well as'inward displacement so that the normal holding capacity of the container is'therebymaintained, and the walls of the container are braced by the ribs and held so asto permit the grouping of a series of containers together without interference with each other due to bulging of adjacent Walls thereof.

I claim:

In combination with v a a sheet metal container for liquid having walls that extend substantially in flat planes, a series of ribs each being formed of sheet metal and shaped so as to 'have' dive rgently disposed sides, the inner edge of one of which sides is contiguous with the corresponding inner edge of its complemental side, and the edge of each side having an outwardly extending flange, said sides being comparatively wider at their lower ends than at their upper ends, said flanges being secured to the inner face of the container-wall, the spacelbetweenthe sides of said rib and the adjacent portion of the container wall constituting "a passageway that is open to the'interior of the container at eachend of the rib.
